Macro partitioning
Reducing household food waste and animal-source food consumption offers the highest synergistic potential for mitigating obesity, environmental pressure, and food demand compared to other interventions like eliminating underweight.
Focus on reducing household food waste and shifting dietary composition away from animal-source foods. These interventions offer the highest synergistic benefits for health and the environment, whereas simply addressing underweight has minimal impact on total food demand.
Reducing household waste, animal-source foods, and overweight could synergistically address multiple symptoms at once, while eliminating underweight would not substantially increase food demand.
Why this rating
Based on the model's decomposition analysis showing food waste exceeds intake by 25-33%, and animal-source food demand grows disproportionately.
